DAVI D BICE JAMES, OF SAN FRANCISCO, CALIFORNIA.

SWINGING SC RAPER AND SCOOP MACHINE.

SPECIFICATION formingpart of Letters Patent No. 735,388, dated August 4, 1903. Application filed November 14, 1902. $erlal No. 131,449. (No model.)

citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented a new and useful Swinging Scraper and Scoop Machine, of which the following is a specification.

My invention relates toimprovements in scrapers; and the objects of myimprovement are, first, to provide an oblong box or scoop of sheet-iron of suitable thickness and dimensions for the purpose desired with one end open and the lower end carrying teeth to receive sand, mud, or gravel and the opposite end of scoop closed with swinging gate hung from top of scoop to retain the material that is drawn into the scoop and also admit the scoop to be unloaded or emptied, the scoop to be suspended below and from an axletree supported by two wheels, the scoop being connected to the round axletree by iron straps and thimbles to allow the scoop to turn freely as the scoop is drawn in sand or other material to fill itself. I attain these objects by the mechanism illustrated in the accompanying drawings, in Which- Figure 1 is a vertical side view of the swinging scoop taking material. Fig. 2 is a top View of the swinging scoop carried upon a round axletree'inserted into wheels. Fig. 3 is a side view ofthe swinging scoop'in p'osition to be emptied.

Similar letters refer to similar parts throu ghout the several views.

The box or scoop scraper A in Fig. 1 is connected by straps B to axletree C, connecting carrying-wheels D, upon which scoop A is carried and hung, tongue E, of any desired pulley I upon axletree C to rear end of scoop Ato control and adjust it, allowing gate end of scoop to lower when filled.

The scoop A is connected with axletree C nearer its front end, so that when it is partially filled and chain F is released by the lever G in the quadrant H the scoop from excess of weight toward the rear end tips backward and offers no resistance to be drawn out of the water to be emptied of its contents, which is done by releasing the lever N, that fastens the gate J. The chain K, the tongue E, with threaded bolt 0, with scoop A, controls pitch of same and regulates the amount of'material to be taken up and prevents the scoop from going too deep.

Figs. 2 and 3 are simply to show more clearly the construction and operationof the swinging scoop-scraper.

I am aware that prior to my invention scrapers have been used for moving sand and earth. I therefore do not claim such a combination broadly; but

What I do claim as my invention, and desire to secure by Letters Patent, is

1. In a scoop-scraper having supportingwheels and axle the combination of a scoop suspended from the axle; a long tongue connected with the axle; a quadrant lever connected withthe forward end of the tongue and a flexible connection between the lever and the rear end of the scoop'substantiall'y as described.

- 2 In a scoop-scraper having supportingwheels and axle the combination of a scoop pivotally connected with the axle, a long tongue attached to the scraper an adjustable connection betweenthe tongue and the forward end of the scoop a quadrant lever attached to the forward end of the tongue and a connection between the lever and the rear end of the scoop.
